LINOTYPE-MACHINE.

Patented April 21, 1908.

Application filed April 1, 1907. Serial No. 365,665.

To all whom it may concern:

Be it known that we, J OHN GLENNIE HoL- BOURNS and HENRY ALEXANDER LoNcHURST, subjects of the King of the United Kingdom of Great Britain andIreland, and residing at 188 Fleet street, in the city of London,England, have invented new and useful Improvements in Linotype-Machines,of which the following is a specification.

This invention relates to linotype machines and has for its object toprovide means for enabling the operator, by one operation, to adjustsimultaneously the mold and the trimming knives, for effecting a changeof body dimension in the linotype produced.

In the accompanying drawings, which are to be taken as part of thisspecification, and read therewith; Figure 1 is a front elevation of asmuch of a linotype machine as is necessary to illustrate the presentinvention: Fig. 2 is a horizontal section taken about on the line 22 ofFig. 1: Fig. 3 is an elevation as seen from the right-hand side of Fig.1, with the mold wheel shown partly in vertical section: Figs. 4 and 5are front elevations of the adjustable mold shown detached, and in twodifferent conditions of adjustment: Fig. 6 is an elevation of theadjusting key: Fig. 7 is a rear elevation of a mold which is adj ustableboth for measure and body dimensions, and Fig. 8 is a vertical sectionon the line 88 of Fig. 7, as seen in the direction indicated by thearrow in the last named figure.

According to the present invention, the body piece 1 of the mold 2 is,as ordinarily, rigidly attached to the mold wheel 3, and the cap plate 4is adapted to slide relatively to such body piece, being guided in suchsliding movement by the projections 5, on the cap plate working inrecesses 6 in the body piece 1, this sliding movement providing for thedistance between the two opposed surfaces of the body piece 1 and capplate 4 being increased and decreased as shown by the two Figs. 4 and 5,for effecting a corresponding increase and decrease in the above-namedbody dimension.

Thecap plate 4, or more strictly speaking, the flange 7 thereof, isprovided with a slotted bearing 8, Figs. 4 and 5, in which is rotatablean eccentric 9 conveniently integral with a concentric boss 10 free torotate in a bearing in the mold wheel 3, as shown best in Fig. 2. Thisboss 10 is formed with a square or otherwise non-circular concentricwhich, the operator can rea hole 11 adapted to receive thecorrespondingly-shaped end 12, Fig. 6, of a key 13, and it is alsoprovided with a concentric collar or flange 14 having notches 15, 16 and17 adapted to be engaged by a tooth or detent 18 hereinafter termed adetent. The detent 18 is free to slide in a suitable recess in the moldwheel 3, in a direction parallel with the axis of rotation of the saidwheel, see particularly Fig. 2, and it is acted upon by a compressionspring 19 which constantly tends to move it into or retain it in, theenga ing position in which it is represented in t e drawings, but whichalso allows it to be pushed by the operator in the opposite directionand thereby disengaged from the collar 14, when the eccentric 9 is to beturned for altering the body dimension of the mold. The detent 18 isprevented from leaving the recess in which it is slidable, by the flange7 of the cap plate 4 against which the spring presses it when it is inengagement with one or other of the notches 15, 16, 17; or any othersuitable means may be provided for limiting the outward movement of thedetent 18.

The fixed trimming knife 20 is secured to the vise frame 21 in theordinar way, and the trimming knife 22 is adjustab y mounted on theadjustable knife block 23 which, as ordinarily, is secured to the viseframe 21 by bolts and nuts 24. In the example illustrated, theadjustability of the trimming knife 22 is secured by roviding the knifeblock 23 with a dovetai groove 25, Fig. 3, in which the said knife, by apart integral therewith of corres onding dovetail shape, is free to bemoved in a horizontal direction. In the adjustable knife 22 there isrovided a slotted bearing 26 (shown in dotte lines in Fig. 1) for aneccentric 27 formed on the rear end of a tubular shaft 28 which is freeto ro= tate in a bearing 29 in the knife block 23, as shown best in Fig.2. On the front end of the tubular shaft 28 is secured a flanged col-1hr 30 having notches 31, 32 and 33, Fig. 1, with which is adapted toengage a detent 34 ivoted to a bracket 35 fast to the knife block 23 andacted upon by a coiled spring 36 which constantly tends to move thedetent rearward into the position in which it engages the notches 31, 32and 33. The detent 34 is provided with a suitable thumb plate orequivalent 37 by pressing upon ily disengage the said detent from one orother of the last named notches, and the said detent has pivotallyconnected with it one end of a push rod 38 capable of being adjusted totwo different ositions, as shown respectively in full and dotted linesin Fig. 3. In one of these ositions, viz., that in which it isrepresented in dotted lines in Fig. 3, the ush rod 38 is inoperative andout of reaci of the mold wheel 3, and in the other osition, viz., thatin which it is shown in ull lines, the push rod is supported by asuitable guide 39 on the knife block 23 in such position that when themold wheel 3 is in the normal or linotype-ejecting position, and thethumb plate 37 is pressed upon by the operator to release the detent 34from the particular notch 31, 32 or 33 with which it is then engaged,the rear end of the push rod 38 engages also with the detent 18 on themold wheel 3 and releases it from its respective notched collar 14.

When it is desired to move the push rod 38 from its operative positioninto its inoperative position, the o erator first moves it sidewise outof the gui e 39, as shown in dotted lines in Fig. 2, and then lowers iton to the lower of the before-named nuts 24 which thereafter supports itin position until the operator next requires to effect an adjustment(for body dlmension) of the mold and knives.

The tubular shaft 28 is provided with a square or otherwise non-circularconcentric hole 40 adapted to receive a correspondingly shaped portion41 of the key 13, which latter is insertible through the front end ofthe said shaft and, when so inserted, ca able of engaging with both ofthe non-circu ar holes 11 and 40 as shown in Fig. 3, when the mold wheel3 is in the normal position or that in which the linotypes are ejectedfrom the mold.

It will thus be seen that when the operator requires to adjust the mold2 and knife 22 for effecting a change of body dimension, all he has todo is to insert the key 13 in the noncircular holes 11, 40, ress backthe thumb plate 37 and turn the ey 13 in the required direction, and,when the desired adjustment has been made, release the thumb plate 37 toallow the detents 18, 34 to rengage their respective notches 15 and 31,16 and 32, or 17 and 33, these notches being so situated as to give allgradations of body dimensions be tween, and including, the maximum andminimum which the machine is adapted to cast.

To enable the before described adjustable mold 2 to be adjusted forcasting linotypes of difierent measure while maintaining the variousjuxtaposed surfaces which are, for variation of body dimension, inmetal-tight sliding contact, the said mold, as shown in Figs. 7 and 8,is provided with a number of changeable liners 42, 43 one of each pairof which, viz., the liner 42, being adapted to be secured to the bodypiece 1, and the other liner 43 of the said )air, being adapted to besecured to the mold cap 4. The last-named attachments are preferablyeffected by means of dovetail ribs and grooves extending longitudinallyof the liners and. mold cap and body piece, the dovetail ribs 44, 45preferably being on the liners 42, and 43 respectively, and the grooves46, 47 being preferably in the body piece 1 and mold cap 1 respectively.The dovetail groove 46 in the body piece 1 is equal in length to thelongest measure of linotype which it is required to cast in the mold 2,and the dovetail groove 47 in the cap plate 4 extends no further towardsthe opposite end of the mold than does the shortest liner 43 which is tobe attached to the said cap plate as shown in dotted lines in Fig. 7,which arrangement for all adjustments, provides for the proper closingof the grooves 46, 47 against the access of the molten metal thereto.The liners 42 and 43 are secured to the body piece 1 and cap plate 4respectively by screws 48, 49 respectively as shown in Fig. 7.

In the arrangement last described the cap plate 4 is formed with onlyone projection 5 which is adapted. to slide within a recess in the liner42 thus effectually closing, with a metal-tight closure, one end of themold, the other end of which is correspondingly closed by the inner endof the liner 43 sliding in metal tight contact with the juxtaposed outerend of the liner 42. By these means the cap late 4 may be adjustednearer to and fart ier from the body piece 1 for obtaining variations ofbody dimension without disturbing the metal-tight character of thejust-mentioned closures.

We claim 2- 1. In a linotype machine, the combination of a mold andtrimming knives both ad. )ted to be adjusted for obtaining linotypes odifferent body dimensions, and eccentrics operatively-connected with themold and one of the knives for effecting the said adjustments theseeccentrics being in alinement with each other when the mold is in theejecting position, and adapted to be rotated simultaneously about acommon axis.
